We made the best experience with https://makandracards.com/makandra/45171-sipgate-+-linphone-setup
The default settings used by the wizard did not work for me. I got authentication errors all the time.
This is what worked for me:
Account name: Sipgate.de
SIP-IP: Your Sipgate ID (see https://secure.live.sipgate.de/settings/phone/, click on phone and select "Show SIP credentials")
SIP-Passwod: You Sipgate password (see link above)
SIP Server: sipgate.de:5060
Proxy: proxy.live.sipgate.de
If you have trouble with CSipSimple, try Zoiper.
